Add together. When adding the parsley rub it together in your palms to make it finer. Blend until smooth. Makes 2 quarts.

Note: Compared to Hidden Valley Ranch, it's a pretty thin recipe. That's part of the reason why I love it... you can pour a little amount all over your salad, and you don't ever have any bites with tons of dressing. Regardless, if you like your ranch thick - add more mayo.
